Docker 安装HBase 并使用_hbase docker安装

一.安装
1.创建docker-compose.yml文件

   

version: '3.1'
    services:
      hbase:
        image: harisekhon/hbase:1.4.7
        container_name: hbase
        restart: always
        ports:
          - 8880:8080
          - 8885:8085
          - 9990:9090
          - 9995:9095
          - 16000:16000
          - 16010:16010
          - 16020:16020
          - 16030:16030
          - 16201:16201
          - 16301:16301
          - 2381:2181
        environment:
          # SERVICE_PRECONDITION: "namenode:50070 datanode:50075"
          - TZ="Asia/Shanghai"
          - LANG=en_US.UTF-8
        volumes:
          - ./hbase_data:/hbase-data
          - ./hbase_zookeeper_data:/zookeeper-data
    networks:
      default:
        driver: bridge

使用docker-compose命令运行：

docker-compose up -d 

2.修改配置文件

  (1).修改hbase-site.xml配置文件
    hbase.rootdir  修改成  hbase.root.dir
  (2).在hbase-env.sh里面添加

export HBASE_DISABLE_HADOOP_CLASSPATH_LOOKUP=true

 (3).重启hbase即可

二.使用
1.建表

    //创建命名空间
    create_namespace 'user'
    //创建表                
    create 'user:sac','student','course1','course2','course3'     

2.插入数据

   

//第一条
    put 'user:sac','2015001','student:S_Name','zhangsan'
    put 'user:sac','2015001','student:S_Sex','male'
    put 'user:sac','2015001','student:S_Age','23'
    put 'user:sac','2015001','course1:C_No','123001'
    put 'user:sac','2015001','course1:C_Name','Math'
    put 'user:sac','2015001','course1:C_Credit','2.0'
    put 'user:sac','2015001','course1:Score','86'
    put 'user:sac' ,'2015001','course3:C_No','123003'
    put 'user:sac' ,'2015001','course3:C_Name','English'
    put 'user:sac' ,'2015001','course3:C_Credit','3.0'
    put 'user:sac' ,'2015001','course3:Score','69'
    //第二条
    put 'user:sac' ,'2015002','student:S_Name','lisi'
    put 'user:sac' ,'2015002','student:S_Sex','female'
    put 'user:sac' ,'2015002','student:S_Age','22'
    put 'user:sac' ,'2015002','course2:C_No','123002'
    put 'user:sac' ,'2015002','course2:C_Name','Conputer Science'
    put 'user:sac' ,'2015002','course2:Credit','5.0'
    put "user:sac" ,'2015002','course2:Score','77'
    put 'user:sac' ,'2015002','course3:C_No','123003'
    put 'user:sac' ,'2015002','course3:C_Name','English'
    put 'user:sac' ,'2015002','course3:Credit','3.0'
    put 'user:sac' ,'2015002','course3:Score','99'
    //第三条
    put 'user:sac' ,'2015003','student:S_Name','wanger'
    put 'user:sac' ,'2015003','student:S_Sex','male'
    put 'user:sac' ,'2015003','student:S_Age','24'
    put 'user:sac' ,'2015003','course1:C_No','123001'
    put 'user:sac' ,'2015003','course1:C_Name','Math'
    put 'user:sac' ,'2015003','course1:C_Credit','2.0'
    put 'user:sac' ,'2015003','course1:Score','98'
    put 'user:sac' ,'2015003','course2:C_No','123002'
    put 'user:sac' ,'2015003','course2:C_Name','Computer Science'
    put 'user:sac' ,'2015003','course2:C_Credit','5.0'
    put 'user:sac' ,'2015003','course2:Score','95'

3.查询

(1).查询命名空间列表  

 

  //show databases;
    list_namespace

(2).查询命名空间(database)下的表  

   

 //show tables;
    list_namespace_tables 'namespace'

(3).全表查询  

 

  //select * from tableName
    scan 'namespace:table'

(4).全表扫面指定的族(根据表下的某个族查询)  

    在nosql中存储数据是将某个对象所有的属性全部存储
    例如关系型数据库中的用户，权限，角色是分表存储，但是nosql中，将某个用户的权限角色都一起存在用户表中;
    其中用户，角色，权限分别属于用户表中的三个族
      
   

scan 'namespace:table',COLUMn=>'用户族'

(5).查询某个族下的指定列的数据

 

   //查询唯一一条 get
    //根据条件查询某条数据
    get 'namespace:table','rowkey','族:列'

   

 //批量查询 scan
    //查询从rowkeyStart到rowkeyStop的数据
    scan 'namespace:table',

{COLUMN=>'族',STARTROW=>'rowkeyStart',STOPROW=>'rowkeySTOP+1'} 
    //查询10条数据
    scan 'namespace:table',{COLUMN=>'族',LIMIT=>10}

(6).根据条件过滤查询

  scan 'namespace:table',FILTER=>"ColumnPrefixFilter('字段条件') AND ValueFilter(=,'substring:内容条件')"
  例:  
 
    //在user库中查询，学生姓名列S_Name包含‘张’的数据
    scan 'user:sac',FILTER=>"ColumnPrefixFilter('S_Name') AND ValueFilter(=,'substring:zhang')"

4.删除数据

(1).根据rowkey删除指定的行    //deleteall rowkey
    deleteall '2015003'
